Rehabilitation of oral function using dental implants is clinically effective and highly predictable. Bone quantity and quality at the implant site both affect the success of the procedure. However, the effect of bisphosphonate (BP) use on mandibular bone quality has not been well documented. The purpose of this retrospective cohort study was to evaluate the bone mineral density (BMD) and cortical thickness of the mandible, as well as the influence of BP use on early implant failure. Twenty-five female patients (≥ 60 years of age) were selected from among 93 candidates with a partially edentulous posterior mandible...

Peri-implant diseases have received much attention since dental implants are generally used in contemporary dentistry. Several contributing factors associated with the development of peri-implant diseases have also been investigated. The prevalence of peri-implantitis has been reported but with great heterogeneity due to a lack of a universally accepted classification system to define the extent and severity of peri-implantitis. Several parameters, including radiographic bone loss, probing depth, bleeding on probing, and suppuration, have been introduced in these reports aiming to assist with clinical diagnosis...

Implant-related reactive lesions of oral mucosa are much more uncommon than the tooth-related ones. The majority of the cases reported, represent pyogenic granulomas (PG) and peripheral giant cell granulomas (PGCG) although other lesions have also rarely been reported. The aim of this paper is to report a rare case of reactive fibrous hyperplasia of oral mucosa around two healing caps in a 65-year-old female patient. The lesion was treated with excisional biopsy and four years later the patient remains free of recurrence...

Maxillary sinus floor augmentation is considered to play a critical role in dental implant treatment. Although many complications, such as maxillary sinusitis and infection, are well known, few reports are available on the risk of surgical ciliated cyst following the procedure. Here we report a case of surgical ciliated cyst following maxillary sinus floor augmentation. A 55-year-old Japanese woman was referred to our hospital because of alveolar bone atrophy in the bilateral maxilla. We performed bilateral maxillary sinus floor augmentation by the lateral window technique without covering the window...

Zirconia is becoming increasingly used as a restorative material for implant-supported restorations, however information is lacking with respect to the minimum thickness of zirconia surrounding the implant components. The purpose of this study is to evaluate the resistance to fracture of different thicknesses of zirconia luted to implant components. Thirty cylinders of zirconia (Prettau, Zirkonzahn) with 13 mm height, designed with indented occlusal surface for loading, and varying wall thicknesses (0.5 mm, 1 mm, 1...

The majority of patients often have functional problems after undergoing jaw reconstruction. These patients require intense rehabilitation, including surgical and prosthodontic procedures to maximize function, esthetics, and to preserve mastication, speech, and appearance. This clinical report describes the rehabilitation of a patient who had a large tumor resection of ameloblastoma of the mandible resulting in hard and soft tissue deficiency. The mandible was reconstructed with an iliac bone graft with simultaneous tumor removal...

This case report aims to describe in detail a complication associated with resorption of regenerated bone following implant placement and ridge augmentation using rhBMP-2 in combination with allograft and xenograft. Bilateral maxillary sinus and ridge augmentation procedures were completed using rhBMP-2 combined with allograft and xenograft. Five months later, significant bone augmentation was achieved which allowed for the placement of 4 implants. Upon stage 2 surgery, significant dehiscence was noted in all implants...

Epidermolysis bullosa (EB) is a hereditary mucocutaneous disorder with several oral and systemic manifestations. Major problems with dental management of such patients are blisters induced from trauma and microstomia. Therefore, fixed implant-supported prosthesis may result in higher levels of satisfaction in complete edentulous EB patients. In several cases, the clinicians encounter with difficulties during the treatment procedure using conventional methods. In following report, oral rehabilitation of a completely edentulous EB patient with fixed implant-supported prosthesis on four dental implants using combination of digital and conventional methods are described...

The anterior loop of the inferior alveolar nerve is a sensitive anatomical feature which should be taken into account during installing dental implants anterior to the mental foramen. Since results regarding its prevalence and length are controversial, this study was conducted. A total of 452 mandible quadrants of 234 patients (age: 50.1±13.3 years, 113 males, 121 females) were studied using cone-beam computerized tomography (CBCT). After reconstructing axial, frontal, and sagittal slices, the region between the most anterior point on the mental foramen and the most anterior part of the mandibular nerve was inspected for signs of anterior loop presence...

This study aimed to identify the preferred crown material by measuring the peri-implant clinical parameters and the concentrations of receptor activator of nuclear factor-κB ligand (RANKL), osteoprotegerin (OPG), and calcium in peri-implant crevicular fluid (PICF) with four different crown materials. A total of 196 patients with a single missing posterior tooth received crown restoration with cobalt-chromium (Co-Cr) porcelain-fused-to-metal (PFM) (n=50), aurum platinum (Au-Pt) PFM (n=48), titanium (Ti) PFM (n=52), or zirconia (Zi) all-ceramic crown (n=46)...

The aim of this study was to assess the effect of DLC (Diamond-like carbon) coating on the removal torque of prefabricated implant screws after cyclic loading. Four groups with two crowns supported by two implants (n=5) were obtained according to splinted and non-splinted prosthesis, using titanium or DLC screw (STi, SC, NSTi and NSC). The prosthetic screws were tightened at 32Ncm, retightened, and the specimens were submitted to 106 mechanical cycles (4Hz/98N). After cyclic loading, loosening torque was evaluated and the final measurements were performed...

GBR is a technique sensitive procedure that routinely involves placement of particulate bone with or without fixation screws and either a resorbable or a non-resorbable membrane. Grafting of the buccal-crestal aspect of the implant site can be particularly challenging as external pressure from the flap or occlusal forces may displace the graft laterally and apically resulting in deficient bone in the desired region. A novel technique for stabilizing a resorbable membrane and underlying particulate graft allowing for predictable bone grafting across multiple edentulous sites...

The objective of this research was to clinically compare peri-implant tissue health of bar-clips versus silicone-resilient liners used with bilateral posterior bars for retaining four implant supported mandibular overdentures. Thirty completely edentulous male patients (mean age 65) were randomly assigned into two equal groups. Each patient received four implants in canine and first molar regions of the mandible using flapless surgical technique. Mandibular overdentures were immediately connected to the implants with bilateral prefabricated instant adjusting bars...

There is controversy in the literature regarding the indicated retentive mechanism for implant supported crowns. When adjacent implants are restored, the restoration can be either screw retained, cement retained, or a combination of cement and screw retained. Adjacent implant supported crowns can be restored as individual implant supported crowns or they can be splinted. A classification system is proposed when adjacent implants are restored. The classification system describes currently available options to restore adjacent implants...

Many dental procedures allow for implant placement in partially or totally edentulous patients. Despite the availability of various implant and abutment types on the market, it often becomes quite challenging to achieve the biological and esthetic goals in a patient who has ridge deficiencies. Where problems will arise is from the lack of adequate bone quality and quantity.1,2 Soft tissue form and maintenance is also a consideration to evaluate.3 Primary reconstructive techniques following segmental mandibulectomy is evolving and improves quality of life...

The lack of compatible prosthetic components can be a complication during oral rehabilitations using outdated implants. The aim of the present clinical report was to describe an alternative technique for the fabrication of a maxillary implant-supported overdenture in a patient with 20-year-old dental implants using castable spherical patterns and ball-attachments. The patient had been wearing a relined bar/clip overdenture in the mandible on four external-hexagon dental implants and a relined complete denture in the maxilla on four internal-hexagon implants due to abutment screw fracture inside of the implants, losing the attachment system...

The recently popularised socket-shield technique involves intentional retention of a section of the remnant root at the time of immediate implant placement to preserve the buccal/proximal bone from resorption. The objective of this systematic review was to assess the literature available on the socket-shield technique and weigh its biological plausibility and long-term clinical prognosis. A Systematic Search was performed in PubMed-Medline, Embase, Web of Knowledge, Google Scholar and Cochrane Central for clinical/ animal studies up to April 2017...
